Local adaptation to climate facilitates a global invasion.

Local adaptation may facilitate range expansion during invasions, but the mechanisms promoting destructive invasions remain unclear. Cheatgrass (), native to Eurasia and Africa, has invaded globally, with particularly severe impacts in western North America. We sequenced 307 genotypes and conducted controlled experiments.

DEPs Induce Local Ige Class Switching Independent of Their Ability to Stimulate iBALT de Novo Formation.

Background: Diesel exhaust particles (DEPs) are leading to a general increase in atopic diseases worldwide. However, it is still unknown whether DEPs induce systemic B-cell IgE class switching in secondary lymphoid organs or locally in the lungs in inducible bronchus-associated lymphoid tissue (iBALT). The aim of this work was to identify the exact site of DEP-mediated B-cell IgE class switching and pro-allergic antibody production.

[Electromyography in childhood patients with tic hyperkinesis and Tourette's syndrome].

Objective: To determine the electromyographic patterns of motor tics in children.

Material And Methods: 130 patients were examined, which were divided into 3 groups: the 1st group included 21 patients with motor tics; the 2nd group included 87 patients with motor-vocal tics; the 3rd group included 22 patients with Tourette's syndrome (ST). The control group consisted of 35 healthy children.

[THE ASSESSMENT OF THE RESEARCH POTENTIAL OF THE AMBULATORY-POLYCLINICAL INSTITUTIONS OF THE MOSCOW HEALTHCARE SYSTEM].

Scientific research and their inclusion in the health care system is an important part of modern medical science. To study the readiness of primary care physicians as well as administration staff to introduce a research component into the national health care system, "The Research Institute for Healthcare Organization and Medical Management of Moscow Healthcare Department" conducted an online survey of two groups of respondents - physicians of primary care settings (n = 593) and heads of outpatient clinics in Moscow (n = 168) in 2021. The results of the study show the insufficient involvement of primary care doctors in research activities in their working places: more than half do not consider scientific activities as a priority, motivating it by the lack of conditions, practical skills, age and health status as well as high level of employment, although they do not reject it in the future.

Dual-longitudinal-mode CW self-sweeping operation in Er-doped fiber laser.

A new type of sweeping operation-dual-mode continuous-wave (CW) self-sweeping-is demonstrated in an erbium-doped fiber laser with a sweeping range of 2.8 nm in a region of 1605 nm. The laser generates two adjacent longitudinal modes of equal intensity, but at some moments of time, one of the modes with lower frequency begins to vanish and a new one with even higher frequency starts to grow.
